   You're looking at the Ruby script not the shell script/exectuable
generated by RubyGems. The shell script/exectuable generated by
RubyGems looks something like:

#!c:/prg/ruby/v186/bin/ruby.exe
#
# This file was generated by RubyGems.
#
# The application 'slideshow' is installed as part of a gem, and
# this file is here to facilitate running it.
#

require 'rubygems'

version = ">= 0"

if ARGV.first =~ /^_(.*)_$/ and Gem::Version.correct? $1 then
  version = $1
  ARGV.shift
end

gem 'slideshow', version
load 'slideshow'


   As mention before the shell script should get placed into your Ruby
interpreter's binary folder (not the gem folder) and you have to
include the Ruby interpreter's binary folder into your execution path
to make it work.

   Cheers.
